Triton Nucleus & C14: Radiogenic Properties & Instability

In summary, the stability of isotopes, such as tritium and carbon-14, is determined by the number of neutrons present in the nucleus. Too few or too many neutrons can lead to instability and radioactive decay. This can be seen in the chart of nuclides, which shows a stability band for each element. The underlying principles behind this stability are still being studied and may involve factors such as the semi-empirical formula and quark theory.

To all: In some detail what makes the tritium isotope of hydrogen radiogenic?

And since C12 and C13 are both stable what makes C14 unstable?

Thanks

In both cases and excess of neutrons!

T has 1 p and 2n. In the deuteron, the pn combination is fairly stable, but adding one more neutron pnn allows for less stability.

Similarly for C14, 6p+8n, versus 6p6n or 6p7n, in C12 and C13, respectively.

Thank you for your reply. I was hoping for a connection to some underlying principle. For example, if you add the right number of neutrons then stability ensues. The wrong number and you get instability.

What is the right and wrong #s criterion.

Perhaps it could be approached through the semi-empirical formula or quark theory?

The former I have a some and the latter only superficial knowledge.

Well there is that. There is more or less a stability band. On either side, one finds a radionuclide, but its not very straightforward. To few neutrons will usually lead to positron emission or electron capture. To many neutrons will lead to beta or alpha decay, but alpha decay is restricted to the heavy elements from Bi on up (Bi 210 is the lightest nuclide to undergo spontaneous alpha emission).

One can find the chart of nuclides here - http://wwwndc.tokai.jaeri.go.jp/CN04/index.html

I'll get back to you on that.

1. What is Triton Nucleus?

Triton Nucleus is the nucleus of the element Triton, which is a radioactive isotope of hydrogen. It contains one proton and two neutrons, giving it an atomic mass of 3.

2. What are the radiogenic properties of Triton Nucleus?

Triton Nucleus is a radioactive isotope, meaning it undergoes radioactive decay. This decay process releases energy in the form of radiation, which can be harmful to living organisms.

3. What is C14 and how is it related to Triton Nucleus?

C14, also known as carbon-14, is a radioactive isotope of carbon. It is not directly related to Triton Nucleus, but both are examples of radiogenic elements.

4. What makes Triton Nucleus unstable?

Triton Nucleus is unstable because it has an excess of neutrons compared to stable isotopes of hydrogen. This imbalance in the number of protons and neutrons causes the nucleus to be unstable and undergo radioactive decay.

5. How does the instability of Triton Nucleus affect its half-life?

The instability of Triton Nucleus affects its half-life, which is the amount of time it takes for half of the atoms in a sample to decay. Since Triton Nucleus is unstable, it has a relatively short half-life of 12.32 years, meaning it decays relatively quickly.
